LIS2DH12 FIFO Watermark interrupt configuration

Posted on June 02, 2017 at 07:35Hello,I am using following resister setting to config the LIS2DH12 to generate FIFO watermark interrupt on INT1 pin, however the INT1 pin always stays LOW, I am not sure what I am missing.INT1 is connect directly to t...

STLM20W87F Output Values Do Not Change

Posted on June 08, 2017 at 04:31Hello:I am using the STLM20W87F temperature sensor in an application, basically, on a PCB to measure ambient temperature.Referring to page 10 of the datasheet, I have the sensor connected with a filter of 1000p / 10K....

LIS2DH12: Interrupt issue with click configuration

Posted on June 07, 2017 at 23:23Hi everyone,For my application I used the LIS2DH12 MEMS in single click configuration. This is my setting:CTRL_REG1 = 0x5F                       // ODR=100Hz, Low Power mode, Z Y X axis enableCTRL_REG4 = 0x00         ...

Accuracy FlightSense

Posted on June 02, 2017 at 11:05Hi everyone !I'm working on the flightsense sensor thanks to the expansion  board X-Nucleo-6180XA1 and a satellite on a STM32F401RE. And I have some questions :I would like to know the accuracy of the sensor ?Also, I ...

Continuous Range measurement VL6180x without API

Posted on June 07, 2017 at 15:08Hey,I am trying to use the VL6180x without an API and want to communicate to it directly by I2C. Therefore I use the USBISS. Performing measurements with single shots works fine. I can also read out the results easily...

L3G4200D - STATUS_REG and Spykes

Posted on June 05, 2017 at 11:40Hi,reading data from L3G4200D i observed some spikes.So i set the BDU :I read before MSB and then LSB for X, Y, then Z such as described in the datasheet.reading the status_reg to know when new data is available i saw...

LSM303AGR mems reading problems.

Posted on May 30, 2017 at 11:39I'm working on LSM303AGR mems and I've some reading problems: when I read x, y, z accelerometer registers in 'normal mode' I get lots of 0 and sometimes a correct value (z value have to be about 1G, not 0), when I set ...

LIS2DH12 communication problem

Posted on May 29, 2017 at 11:13Hello, I am using two LIS2DH12 sensors in my project. I am using I2C communication interface. The one with the address pin high (IC4, address 0b0011001x) is working OK, but the one with the address pin low (IC5, addres...
